Question 692037
{{{ f(x) = 16x^2 - 63861x + 63722378 }}}
given:
{{{ 164 = 16x^2 - 63861x + 63722378 }}}
use quadratic formula
{{{ x = ( -b +- sqrt( b^2 - 4*a*c )) / (2*a) }}} 
{{{ x = ( -(-63861) +- sqrt( (-63861)^2 - 4*16*63722378 )) / (2*16) }}} 
{{{ x = ( 63861 +- sqrt( (-63861)^2 - 4*16*63722378 )) / 32 }}} 
My calculator can't handle these numbers. If you have a scientific
calculator, you should be able to solve for {{{ x }}}
